Type II supernovae from prompt explosions
Physical Review Letters, 1987Evidence is cited that supernova 1987A involved a large explosion energy, of about (2-3) x 10 to the 51st ergs. Such large explosion energy has not come from delayed shocks to date, nor is it likely to. Improved physics in the presupernova evolution, especially the inclusion of Coulomb interactions, has brought the iron-core mass down by less than ...

1974
The supernova of 1923 in M83 has only a partial, but continuous light curve (Figure 1) based entirely on Lampland’s assiduous observations at Lowell Observatory from May 5 to July 1, 1923 (Lampland, 1936). There are only three other published observations from Harvard; the SN was invisible on patrol camera plates (m> 14.0 and m> 13.5) on April 6 and 23

The Energetics of Type II Supernovae
1984The energetics of type II supernovae is considered within the gravitational implosion-explosion picture. The total (internal plus gravitational) energies of different parts of the star are calculated, when they are in, or close to, hydrostatic equilibrium.

Supernova 1993J as a spectroscopic link between type II and type Ib supernovae
Nature, 1993Supernova 1993J in the nearby galaxy M81 is one of the closest - and hence brightest - supernovae to be witnessed this century. The early spectrum of SN1993J showed the characteristic hydrogen signature of type II supernovae, but its subsequent evolution is atypical for this class of supernova. Here we present optical and infrared spectra of SN1993J up

Nucleosynthesis in type I and type II supernovae
Advances in Space Research, 1984Abstract Nucleosynthesis in type I and type II supernovae is reviewed in the framework of existing models and observational constraints. Major observational constraints for type II supernova (SNII) are the existence of neutron stars in the center of SNII remnants and the observation of hydrogen lines in SNII spectra. The first fact is interpreted by

On the Frequency of Type I and Type II Supernovae
1974I would like to present some simple considerations concerning the frequency of supernovae of both types and the mass range of their stellar progenitors which I have tried to deduce from the statistics given by Tammann (1970) for Sb and Sc galaxies only, and from some other data of other authors (Bertola and Sussi, 1965; Barbon, 1968) I will just ...
